Product DescriptionEquipped with an Image Stabilizer and high zoom ratio, the Canon EF 28-135mm standard zoom lens delivers sharp, natural-looking pictures virtually ever time. The lens is particularly handy for places where flashes are prohibited, as it excels in dim lighting without requiring a flash or a tripod. Other features include a ring-type USM for swift, silent autofocusing and full-time manual focusing; a close focusing distance of 20 inches; and a maximum aperture of f/3.5 to 5.6. The lens carries a one-year warranty.
